[BUG] ??? Assignment without variable declaration

Hello!
The class variables are kept (declared), even if explicitly removed.
It is ok? (i.e. the messages are not recompiled.)
I had expected either a forced recompilation of the class messages (while
removing the class variable), or a run time error.

Procedure:
.....................................................
1. Create a new Class ->
Object subclass: #MyFirstClass
instanceVariableNames: 'alpha'
classVariableNames: ''
poolDictionaries: ''
category: 'Patrick-Nodes'
.....................................................
2. Create new messages in category accessing ->
alpha: aNumber
alpha := aNumber
alpha
^ alpha
.....................................................
3. Try it ->
x := MyFirstClass new alpha: 12.
x alpha 12 (Print)
x beta (Print) MessageNotUnderstood: MyFirstClass>>beta
UNTIL NOW, ALL WORK VERY FINE... :))
.....................................................
But
.....................................................
4. Now remove Variable alpha
Object subclass: #MyFirstClass
instanceVariableNames: ''
classVariableNames: ''
poolDictionaries: ''
category: 'Patrick-Nodes'
.....................................................
4. Try it ->
x := MyFirstClass new alpha: 24.
x alpha 24 (Print)
Works also fine, but wrong :( because variable alpha does not exist anymore.
It should provoke a run time error, isn't it?
